## Change the Theme

The same way you could set the syntax highlighting theme with the key `"syntaxHighlight.theme"` (notice that it has a dot in the middle):

{* ../../docs_src/configure_swagger_ui/tutorial002.py hl[3] *}

That configuration would change the syntax highlighting color theme:

        @Override
        public String toString() {
            return name + ":" + version;
        }
    }

    public enum ArtifactType {
        DATA_STORE("fess-ds"), //
        THEME("fess-theme"), //
        INGEST("fess-ingest"), //
        SCRIPT("fess-script"), //
        WEBAPP("fess-webapp"), //
        THUMBNAIL("fess-thumbnail"), //
        CRAWLER("fess-crawler"), //
        UNKNOWN("jar");

* **`200`** and above are for "Successful" responses. These are the ones you would use the most.
    * `200` is the default status code, which means everything was "OK".
    * Another example would be `201`, "Created". It is commonly used after creating a new record in the database.

There are **tests for both Pydantic v1 and v2**, and test **coverage** is kept at **100%**.

### Changes

* There are **new parameter** fields supported by Pydantic `Field()` for:

    * `Path()`
    * `Query()`
    * `Header()`
    * `Cookie()`

These types that have internal types are called "**generic**" types. And it's possible to declare them, even with their internal types.

To declare those types and the internal types, you can use the standard Python module `typing`. It exists specifically to support these type hints.
